Car idles very rough. When car is started it reves up to about2 1/2 rpms. When driving down highway the car will slightly*****. When the wheel turns there is a slight grinding noise in the front. When the car idles it acts like it wants to die. I have had the front and back manifold gaskets changed. I have checked the transmission fluid and it seems to be fine.
